Videochatting With My Sister

Melissa is the older of my 2 sisters. She's 2 years older than me. She has always been my best friend. We talk to each other every day. She's the first person I call whenever something good, or bad, happens to me. A few months after I learned to masturbate we started watching each other as we did it. After she moved to California for college we'd only be able to masturbate together once, maybe twice a year. About 10 years ago we started videochatting a few times a week. After a few months we figured out that we could watch each other masturbate as we videochat. Last December Melissa texted me saying she was home from work & asked if I wanted to videochat. I texted back saying sure. We both got Skype going. When I saw her on my screen I could only see her from the neck up. I asked her why she had her webcam zoomed in and she said she had a surprise. My brother-in-law had dared her to do something. She had the camera zoom out and I was shocked to see that she had gotten her nipples pierced. I kept staring at them. After a minute she asked me if I liked them. I told her they looked cool. She said the nipple rings make masturbating a lot more fun. She has very sensitive nipples. We got to talking about some other stuff for a while. Then all of a sudden she said she needed to cum and asked if we could masturbate tgether. I said sure and I scooted back so she could see all of me on my bed. She had her 2 vibrators right next to her on the bed. I told her to put one in her pussy and one in her asshole and turn them on at the same time. When she turned them on she squealed pretty loudly. She began pushing the vibrator in and out of her pussy while she played with her clit. She left the one in her asshole alone & let it vibrate. I started stroking my cock as I watched her. I have a vibrator that I use on my balls sometimes. Melissa told me to get it out and let it touch the base of my cock with it on. When I did I almost came right then. I was able to hold it off. We continued to masturbate together for about 10 more minutes. I really wanted to see Melissa cum. I told her to pull the vibrator out of her ass and put it on one of her nipples. She did and a few seconds later she started covulsing and moaning very loud. She screamed "OH FUCK I'M CUMMING!" A few seconds later she pulled the vibrator out of her pussy. Fluids gushed out. I was so shocked at the sight of her squirting that I stopped stroking my cock. As her orgasm subsided, Melissa kept saying "Oh fuck oh fuck oh fuck!" She laid back on her bed for a minute. She sat back up and asked if I was gonna finish. I said I was just waiting so she could watch. She told me to stroke as fast as possible while touching the vibrator to the base of my cock. I started cumming in less than a minute. My orgasm was so strong my legs were shaking. It had been over a year sine I had cum that hard. We told each other good night & I turned off my laptop. I looked on the floor and there was some cum about 6 feet from where I was sitting. It seems like my best orgasms are when I'm masturbating with Melissa.
